HTML5 User-agents must parse any byte sequences as HTML5 document if the
Content-Type is text/html.

HTML5 requires **authors** to write the prolog, not user-agents. Lacking
prolog just turn the user-agents to quirks mode.
Note that quirks mode doesn't mean "do whatever you consider it quirks."
Parsing quirks mode document is also completely spec'ed.

No, not at all. Rather, it is required by the spec to use HTML5 parser
to parse all byte sequences sent with "Content-Type: text/html".
Could you please stop spreading an unfounded rumor such as "Firefox is
wrong because it ignores the lacking of HTML5 prolog"?
